Printed in the United States of America ISBN: 1-58537-117-3ANSI/ESD STM9.1-2006(This foreword is not part of ESD Association Standard Test Method STM9.1-2006)FOREWORD This standard is intended to provide a test method for evaluating the resistance of static control footwear. This standard does not include heel straps, toe grounders and booties. This standard is limited to defining procedures for measuring the electrical resistance of footwear only and does not address electrical resistance through a person or in combination with floor materials. A common source of electrostatic charge in a work environment is the separation of the foot from the floor, resulting in the generation of electrostatic charge that can accumulate on personnel. The effect of this generation and accumulation can be minimized by the appropriate selection of footwear. To effectively control electrostatic charges, footwear must be used in conjunction with ESD floors or floor materials as defined in ANSI/ESD S7.1. Static control footwear may also pose an electrical hazard unless properly designed and worn in appropriate environments. The test method described in this document will not guarantee electrical hazard reduction. This standard was originally designated ESD S9.1-1995 and was approved on June 5, 1995. Standard Test Method ANSI/ESD STM9.1-2001 was a reaffirmation and redesignation of ESD S9.1-1995 and was approved on February 4, 2001. Standard Test Method ANSI/ESD STM9.1-2006 is a reaffirmation of ANSI/ESD STM9.1-2001 and was approved on June 11, 2006. All documents were prepared by the 9.0 Footwear Subcommittee.

Both test leads shall be isolated from ground. 5.1.2 Electrodes The positive electrode shall consist of a piece of aluminum foil. It shall uniformly contact the maximum amount of the surface area achievable on the inner sole of the footwear under test. The aluminum foil shall be replaced for each new test cycle, or when torn. The negative electrode shall consist of a stainless steel plate larger than the bottom of the footwear, which is placed on an insulative surface. The resistance of the insulative surface shall be greater than 1 x 1013 when measured per ASTM D-257. 5.1.3 Weight Twenty-five pounds (11.35 kg) of metal shot (# 6 or finer) in a bag or bags sufficiently flexible so that when filled with shot they shall conform to inside of the footwear. 5.1.4 Environmental Test Chamber An enclosed chamber capable of controlling relative humidity to 12% RH (± 3%) and 50% RH (± 5%), and temperature to 23 °C (± 3 °C). The humidity indication instrumentation shall be accurate to ± 3% RH in the operation range and traceable to national standards, such as National Institute of Standards and Technology (NIST) in the United States, or to international standards. 5.1.5 Calibration Requirements The test equipment used shall be calibrated periodically in accordance with the manufacturers' recommendations, with a maximum of one year between calibrations. Calibration shall be traceable to national standards, such as NIST in the United States, or to international standards. 5.2 Test Procedure / Conditioning 5.2.1 Specimen Pre-conditioning 5.2.1.1 Cleaning The bottom and inner sole of the specimen shall be wiped with a dry cloth to remove dust. The negative electrode shall be cleaned with a minimum 70% isopropanol-water solution.2ANSI/ESD STM9.1-20065.2.1.2 Humidity Conditioning Test shall be conducted at humidities specified below. 5.2.1.2.1 Low Humidity After cleaning, the samples shall be placed in an environmental chamber preset to 12% (± 3%) relative humidity and 23 °C (± 3 °C). Pre-conditioning of the samples shall be a period of at least 72 hours. 5.2.1.2.2 Moderate Humidity After cleaning, the samples shall be placed in an environmental chamber preset to 50% (± 3%) relative humidity and 23 °C (± 3 °C). Pre-conditioning of the samples shall be a period of at least 72 hours. 5.2.2 Test Configuration The negative electrode shall be placed on the insulative surface described in 5.1.2 and electrically connected to the negative sensing lead of the meter. The aluminum foil shall be inserted into the footwear ensuring that uniform contact with maximum amount of the inner sole is achieved. Fill the footwear with the flexible bags of shot, ensuring that the shot conforms to the footwear. Since footwear styles and sizes vary, it will be necessary to place the excess shot over the top of the footwear. The footwear shall be placed on the negative electrode such that no part of the footwear overhangs the edge. No part of the shot bags shall touch the negative electrode. Connect the positive source lead of the meter to the aluminum foil. Resistance testing shall be conducted in the environmental chamber (Figure 1). NOTE: The resistance of the support surface will not affect the electrical resistance measurement of the sample under test. 5.2.3 Resistance Measurement Procedure 5.2.3.1 Clean footwear per 5.2.1.1. 5.2.3.2 Condition footwear per 5.2.1.2.1 (Low Humidity). 5.2.3.3 Set up the test configuration per 5.2.2. Set the resistance meter to 100 volts DC. Apply the test voltage and record the resistance of the footwear after the reading has stabilized. Remove test voltage and electrode connection. 5.2.3.4 Clean footwear per 5.2.1.1. 5.2.3.5 Condition footwear per 5.2.1.2.2 (Moderate Humidity). 5.2.3.6 Repeat 5.2.3.3 for all samples.3ANSI/ESD STM9.1-20065.2.4 Reporting of Test Results Report all resistance values in ohms. Also report test date/time, test equipment used, environmental pre-conditioning time, temperature, relative humidity, footwear identification and the location of the test. Figure 2 is provided as an example. NOTE: Refer to ANSI/ESD S20.20 for electrical resistance limit for static control footwear. NOTE: It is recognized that some hygroscopic materials (such as, but not limited to, leather) may have results that fluctuate and do not remain within a specified minimum or maximum resistance range as the environmental conditions change.4ANSI/ESD STM9.1-20065 Figure 1.

Test Result FormANSI/ESD STM9.1-20067ANNEX A Fabrication of Shot BagNumber 6 shot is fine and may fall through the fabric weave, especially knit socks. Constructing 2 to 3 inch (4.68 – 7.02 cm) tubes from a tightly woven fabric is recommended.Use of 25 lbs (11.35 kg) of weight.After considerable research it was determined that while weight is a variable when measuring the resistance of footwear, after 25 lbs (11.35 kg) there is no significant difference in the electrical resistance readings. Therefore 25 lbs (11.35 kg) of weight is required.Number 6 shot was chosen because it would most easily conform to the inside surface of any footwear size and lends itself to even weight distribution.。

1.General
Conductive footwear enables the step voltage induced by walking to be discharged. The footwear consists of a non-slip outer sole which conducts over its entire surface, and uppers consisting of material used by the relevant manufacturer.
Contact surfaces must be incorporated between the insole and the outer conductive sole.
Ideally the complete area of the foot should have contact.
The minimum requirement, however, is contact with the ball and heel of the foot.The following conditions must be adhered to:
In order to retain full function, the soles of the conductive shoes must be cleaned if they become soiled.
Non-conductive inserted soles prevent discharge from the shoe, and should not be used.
The function of the conductive footwear should be checked daily before entering the ESD protective area (EPA).
During manufacture of the ESD footwear, the manufacturer must adhere both to the DIN EN 344-347 norms for safety shoes, protective shoes and occupational shoes and also to the ESD norm DIN EN 61340-5-1.
2.Function
The discharge capability of the ESD shoes is –in co-ordination with the conductivity of the floor surface –a measure for the earthing of the persons involved. Contact surfaces which discharge current to the conductive sole represent the discharge route to the floor surface. In the case of critical floors (epoxy resin), a walking test is necessary.
The norm stipulates the documentation of the test on a daily basis.

To ensure full functionality, conductive footwear must fulfil the following criteria:
•ESD in accordance with DIN EN 61340 (0.75 to 35 Mohm)
•Slip-resistant in acordance with DIN 4843 part 100 -R2
•resistance to wear in accordance with DIN EN 345-1
•resistance of temperatures up to 180° C
•resistance to acid and alkaline
•resistance to oil and petrol
•resistance to cutting
•non-shrink
•no wear debris

Electric contact resistance
DIN EN344 to 347 differentiates between three distinct areas
conducting< 10Ûohms
anti-static10Ûto 10ßohms
non-conductive > 10ßohms
Die DIN EN 61340-5-1 differentiates between four distinct areas conducting< 10Øohms
conductive10Øbis 10Ûohms
discharging10Ûbis 10××ohms
non-conductive > 10××ohms
According to the ESD norm DIN EN 61340-5-1, the permissible range for measurement on the metal plate is from 4,5 x 10Úto 1,0 x 10Þohms.
If the ESD shoe-to-floor system is used, the range is further restricted by the norm to:
7.5 x 10Ûto 3.5 x 10Ýohms
It is important to ensure adherence to the overall system, which depends on the Interaction between footwear and above all the floor surface.。
